HEATING-STOVE.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed March 1, 1907. Serial No. 360,008.

To all whom it may concern:

Be it known that I, CLAY WV. BAKER, a citizen of the United States, residing at Delphos, in the county of Ringgold and State of Iowa, have invented certain new and useful Improvements in Heating- Stoves, of which the following is a specification.

This invention contemplates certain new and useful improvements in heating stoves, and the invention has for its object an improved construction'of stove attachment in the nature of a radiator or drum adapted to be placed in or incorporated with the body of the stove, and designed to increase the thermal efficiency or radiating properties of the latter.

The invention consists in certain constructions and arrangements of the parts which I shall first hereinafter describe and then point out the novel features in the appended claim.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which 2- Figure 1 is a vertical sectional view of a stove embodying the features of my invention; Fig. 2 is a horizontal sectional View thereof on the line rx of Fig. 1; Fig. 3 is a perspective view of the drum detached.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawing, the numeral 1 designates the body of a stove, which is provided with a basket or other form of grate 2, ash pit 3 and ash pit door 4:, and combustion chamber or magazine 5, into which one or more doors 6 open. At its upper end the stove body 1 is provided with an outward bulge 7, which consists of an annular enlargement of the combustion chamber and which is connected at any desired point to the smoke pipe or outlet flue 8.

Fitting within the stove body 1 and supported therein in any desired manner, being either a permanent part, or a temporary attachment to the stove, as desired, is a ,drum 9, embodying a plurality of tapered walls that are spaced from each other as shown. The outermost wall 10, tapers downwardly as shown and joins the base of the inter mediate or middle wall 11, which latter tapers upwardly and is in turn connected by a ring to the downwardly tapering innermost wall 12.

13 and 13* designate respectively removable lids for the lower and upper ends of the space within the downwardly tapering innermost wall 12. The space between the inner wall 12 and intermediate wall 11 communicates with the annular enlargement 7 and through the same with the smoke pipe 8 by means of a cross passage formed by one or more tubes 14.

15 designates a casting which is U-shape as shown in cross section and which enibraces the lower ends of the outer and middle walls, so as to protect the same from the. direct action of the heat.

As clearly illustrated in the drawing, the outer and middle walls terminate at a point opposite the fuel doors 6, to form a recess at this point, and taper downwardly on both sides towards the rear side of the stove.

In the operation of the stove the fuel may be fed thereto either through the doors 6 in the side of the stove or through the top of the stove as may be found the most desirable. In the former instance the lower end of the innermost wall 12 is closed by the removable plate 13 as shown in Fig. 1 and the said wall incloses an air space, while in the latter instance a cover 20 is placed at the upper end of the innermost wall and the wall serves as a magazine to receive the fuel and feed it downwardl upon the grate as required. The heated products of combustion rising from the burning fuel are divided by the casting 15 at the lower end of the walls 10 and 11 and follow different paths leading to the smoke pipe 8. A portion of the products of combustion passes between the stove body and the outermost wall 10 and enters the annular chamber formed by the bulge 7 and thereby heats both the stove body and the outermost wall 10. The remaining portion of the products of combustion rises between the innermost wall 12 and the intermediate wall 11 and passes through the tubes 14: into the bulged portion 7 of the stove body. It will thus be readily apparent that the air within the annular space inclosed by the walls 10 and 11 will become highly heated and that this heated air will rise and enter the room, thereby greatly increasing the heating efficiency of the stove. In a similar manner when the closure 13 is in position at the bottom of the innermost wall 12, the air within the space inclosed by the said innermost wall will become heated and rise into the room.

16 designates a deflector flange which is segmental as shown and which is located between the walls of the drum 9 and the body of the stove, extending across the lower wall of the bulged portion 7, so as to do away with a direct draft out through the smoke pipe 8 and serving to spread the flame more evenly over the walls of the drum. In addition to this spreader or deflector 16, I preferably provide a damper 17 in the pipe 14.

Having thus described the invention, what is claimed as new is A stove comprising a body portion forming a fire chamber provided at its upper end with an annular enlargement, a top provided with openings and resting upon the body portion, and a grate in the lower end of the body portion, a drum suspended within the body portion above the grate, and embodying three concentric walls, the outermost wall being spaced on all sides from the adjacent wall of the body portion, the intermediate wall being connected at its lower edge to the outermost wall and forming therewith an upwardly opening air space communicating with the body portion of the stove, underneath the top, and the innermost Wall being connected to the upper edge of the intermediate wall and providing therewith a downwardly-opening annular space communicating with the fire chamber, removable lids for the upper and lower ends of the space contained within the innermost wall, a smoke pipe secured to the annular enlargement of the body portion and leading upwardly therefrom, and a deflector mounted in the annular enlargement underneath the smoke pipe and extending horizontally in both directions therefrom and projecting inwardly with its inner edge in contact with the exterior of the outer wall of the drum, and a tube extending from the air space between the innermost and intermediate walls, through the outermost wall into the annular enlargement, as and for the purpose specified.

In testimony whereof I aflix my signature inpresence of two witnesses.
